Monk's Best Friend
Appa led a simple life, or so he would say if you could get him to talk. Much of it was sleeping, eating, and flying. What Appa would never say, even if flying bisons could talk, was that his simple life got a little lonely sometimes. When he was young, there were many flying bison around; his siblings, his mother, and many others. Now, it seemed it was just him. Luckily, Appa had a constant through this, that made his loneliness a little more bearable. For even as the monk has his best friend, he is the bison's best friend.
